The global and local climate is changing. Current climate trends show that the Philippines, like the rest of the world, has exhibited increasing temperatures, with observed mean temperature increase of 0.64 °C or an average of 0.01 °C per year-increase from 1951- 2010. In the last 59 years, maximum (daytime) and minimum (nighttime) temperatures are also seen to have increased by 0.36 °C and 0.1 °C, respectively. Moreover, the analysis on tropical cyclone passage over Luzon, Visayas and Mindanao using a 30-year running mean shows that there has been a slight increase in the number of cyclones in the Visayas during the 1971-2000 period as compared with the 1951 to 1980 and 1960- 1990 periods (PAGASA 2011).
